068 1 bit shift right −[ SHR1 A ]−Shifts data of A 1 bit to the right
(LSB direction). The carry flag
changes according to the result.2 6.8 164
069 1 bit shift left −[ SHL1 A ]−Shifts data of A 1 bit to the left
(MSB direction). The carry flag
changes according to the result.2 6.8 165
070 n bit shift right −[ A SHR n → B ]−Shifts data of A n bits to the
right (LSB direction) and stores
the result in B. The carry flag
changes according to the result.

071 n bit shift left −[ A SHL n → B ]−Shifts data of A n bits to the left
(MSB direction) and stores the
result in B. The carry flag
changes according to the result.

074 Shift register D SR Q
S (n)
E A
When shift input (S) comes ON,
shifts the data of specified shift
register 1 bit to the left, and
stores data input (D) state into
A. This operation is enabled
while enable input (E) is ON.
The carry flag changes
according to the result.
Shift register: n devices starting
with devi ce A.

shift register D DSR Q
S (n)
E
L A
When shift input (S) comes ON,
shifts the data of specified shift
register 1 bit to the left or to the
right depending on direction
input (L). This operation is
enabled while enable input (E) is
ON. The carry flag changes
according to the result.
Shift register: n devices starting
with devi ce A.
Direction: Left when L is ON,
right when L is OFF
